Ultracoherent superconducting cavity-based multiqudit platform with error-resilient control
Taeyoon Kim, Tanay Roy, Xinyuan You +26
Realizing the promise of quantum computing requires simultaneously increasing Hilbert-space size and coherence times. While qubit-based architectures have long been the dominant pa…
Efficient Floating-Point Arithmetic on Fault-Tolerant Quantum Computers
José E. Cruz Serrallés, Oluwadara Ogunkoya, Do{g}a Murat Kürkçüo{g}lu +5
We propose a novel floating-point encoding scheme that builds on prior work involving fixed-point encodings. We encode floating-point numbers using Two's Complement fixed-point man…
Benchmarking the performance of a high-Q cavity qudit using random unitaries
Nicholas Bornman, Tanay Roy, Joshua A. Job +4
High-coherence cavity resonators are excellent resources for encoding quantum information in higher-dimensional Hilbert spaces, moving beyond traditional qubit-based platforms. A n…
An Improved Bound on Nonlinear Quantum Mechanics using a Cryogenic Radio Frequency Experiment
Oleksandr Melnychuk, Bianca Giaccone, Nicholas Bornman +9
There are strong arguments that quantum mechanics may be nonlinear in its dynamics. A discovery of nonlinearity would hint at a novel understanding of the interplay between gravity…
Demonstrating the Potential of Adaptive LMS Filtering on FPGA-Based Qubit Control Platforms for Improved Qubit Readout in 2D and 3D Quantum Processing Units
Hans Johnson, Nicholas Bornman, Taeyoon Kim +3
Advancements in quantum computing underscore the critical need for sophisticated qubit readout techniques to accurately discern quantum states. This abstract presents our research…
